Title (EN) WATER COMPOSITIONS
(FR) COMPOSITIONS DESTINEES A DES TRAITEMENTS DES EAUX
Abstract: front page image
(EN)Water to be utilized is reacted with soda ash and lime to produce a less corrosive and foulant water. Reaction sludges are fed to a desulfurization unit, where SO¿x?, NO¿x? and CO¿2? abatement occurs; other industrial waste sludges and/or waters and/or gases can also be utilized in such connection. The figure is one of the possible process schemes of present invention.
(FR)On fait réagir une eau que l'on souhaite utiliser avec de la soude calcinée et de la chaux pour la rendre moins propice à la corrosion et aux salissures. On déverse les boues de réaction dans un dispositif de désulfuration où intervient un appauvrissement en SO¿x?, NO¿x? et CO¿2?; on peut aussi faire subir ce traitement à d'autres boues et/ou eaux et/ou gaz provenant de déchets industriels. La figure publiée correspond à l'un des schémas de traitement possibles concernant le processus inventé.
